Property Tax in Stanwood / Camano Island, WA: One Framework, Two Assessors
Washington has no state income tax, which puts more weight on property tax statewide -- and in this specific market, that weight is administered by two entirely separate county governments depending on which side of the Camano Gateway Bridge a property sits on. This page explains the shared statewide framework and the real two-county split honestly, without guessing at a specific current rate for either side.
Why This Market Has Two Tax Bills, Not One
The City of Stanwood is an incorporated Washington city inside Snohomish County -- it was incorporated on October 19, 1903, and remains today under Snohomish County's property-tax jurisdiction, with the Snohomish County Assessor's Office responsible for valuing Stanwood property and administering exemption programs. Camano Island, by contrast, is unincorporated: it is not its own city or town at all, but rather territory of Island County, the same county government that administers Whidbey Island to the west across Saratoga Passage. The Island County Assessor's Office values Camano Island property and certifies levy rates completely independently of Snohomish County's process.
This means a Stanwood property owner and a Camano Island property owner, even living a five-minute drive apart across the Camano Gateway Bridge, are getting entirely separate tax bills from entirely separate county offices, layered with entirely separate sets of local taxing districts (city, fire district, library district, and so on, which differ by side). Treating 'Stanwood/Camano Island property tax' as one number to budget against is a real, easy mistake for a buyer relocating from a market where a single county or city handles everything -- and this page exists specifically to head that mistake off.
Washington's Shared 1% Levy-Limit Framework
Even though the two counties administer tax bills independently, both operate inside the same statewide legal framework. Washington's Department of Revenue describes a statutory '1% levy limit' that constrains how much most taxing districts -- cities, counties, school districts, fire districts -- can grow their total regular property tax levy from one year to the next without voter approval of a levy lid lift or a new voted levy. This traces back to a series of statewide ballot measures, including Referendum 47 in the 1990s, that reshaped how the state limits property tax growth.
The important nuance for a buyer here: that 1% figure caps growth in a taxing district's total levy amount, not an individual owner's tax rate or bill as a percentage of home value. Assessed values (which can and do rise faster than 1% in a hot local market), voter-approved special levies (school bonds, fire district EMS levies), and each taxing district's own budget decisions all still shape what an individual owner actually pays -- on both sides of the bridge. Confirm the current mechanics with the Washington Department of Revenue directly.
What Snohomish County Administers for Stanwood
Stanwood property owners deal with the Snohomish County Assessor's Office for valuation and exemption programs, and Snohomish County's Treasurer for billing and collection -- the City of Stanwood's own site directs residents to the county for detailed parcel and tax information rather than running a separate city tax office. As an incorporated city, Stanwood property is also subject to a municipal levy layer that unincorporated Snohomish County land is not, on top of the county's own levy, the Stanwood-Camano School District's levies and bonds, and any applicable fire district levy.
This page does not state a specific current combined Snohomish County/Stanwood levy rate or a typical annual tax bill figure, since no confirmed current number was found this research pass that this site can stand behind. Confirm current rates and a specific parcel's assessed value directly with the Snohomish County Assessor's Office (snohomishcountywa.gov).
What Island County Administers for Camano Island
Camano Island property owners deal with the Island County Assessor's Office, which the county's own site describes as managing all real property appraisals, exemption programs, and tax roll certification for both Whidbey and Camano Islands -- meaning the same office that handles Camano's valuations also handles Whidbey Island's, a genuinely different administrative reality than a Stanwood buyer moving from a mainland, single-city tax system might expect. The Island County Treasurer's Office sends the actual tax bill, which shows both the assessed value and the certified levy rate for the specific parcel.
Aggregator site Ownwell cites Camano Island's median effective property tax rate at roughly 0.76%, describing it as below both the Washington state median (roughly 0.92%) and the national median it references -- but this page treats that as a secondhand estimate, not an independently verified current rate, and notes that Ownwell's own description flags meaningful variation across Camano Island subdivisions due to local improvement districts. Confirm the actual current levy rate and assessed value for a specific parcel directly with the Island County Assessor's Office (islandcountywa.gov).
The Stanwood-Camano School District: One Shared Levy That Crosses Both Counties
Here's a genuine wrinkle worth understanding: the Stanwood-Camano School District serves both sides of this market -- 11 schools and roughly 4,861 students, including Elger Bay Elementary and Utsalady Elementary on Camano Island itself alongside Cedarhome, Stanwood, and Twin City Elementary schools in and around the city of Stanwood, feeding into the shared Port Susan Middle School and Stanwood High School. That means a single school district's levies and bond measures apply to property owners on both sides of the county line, even though the county-level and city-level portions of the tax bill are entirely separate.
This is one of the few taxing entities that genuinely unifies this two-county market rather than splitting it, and it's worth understanding when evaluating school-levy ballot measures -- a bond or levy vote affects Stanwood and Camano Island property owners together, regardless of which county Assessor ultimately bills each of them.
The Rates We Won't Guess
In the interest of not printing a number this site can't stand behind: this page does not state a specific current combined levy rate, dollar-per-$1,000-of-assessed-value figure, or typical total annual property tax bill for either a Stanwood or a Camano Island home. Aggregator estimates exist for both areas but weren't verified against a fully-loaded primary source from either county Assessor during this research pass.
The correct places to get this year's actual figures are the Snohomish County Assessor's Office directly for a Stanwood parcel, and the Island County Assessor's Office directly for a Camano Island parcel -- not a secondhand estimate here or on a real estate aggregator site.
What This Means When You Budget a Purchase
First, identify which county actually has jurisdiction over the specific parcel you're considering before assuming any tax figure applies -- a property with a Stanwood mailing address can still, depending on exact location, be either inside city limits (Snohomish County plus city levy) or in unincorporated Snohomish County nearby (no city levy), while any Camano Island property is unincorporated Island County regardless of address conventions. Second, don't anchor a budget to a third-party aggregator's estimated rate -- confirm the specific parcel's current assessed value and certified levy rate with the correct county Assessor directly.
Third, remember that if you or a household member may qualify for a senior, disabled-person, or veteran property tax exemption or deferral program, both Snohomish County and Island County administer these under the same statewide Washington Department of Revenue rules, but through separate county-level applications -- ask the applicable county Assessor's office directly about eligibility rather than assuming either way. None of this is legal or tax advice; confirm every current figure directly with the Snohomish County Assessor, the Island County Assessor, the Washington State Department of Revenue, and a licensed Washington tax professional before making a purchase or relying on any number here for a financial decision.

Washington's lack of a state personal income tax and the resulting reliance on property tax is confirmed via the Washington State Department of Revenue's own tax pages. The statutory 1% property tax levy limit framework and its roots in ballot measures including Referendum 47 are confirmed via the Department of Revenue's own published guidance and Ballotpedia's entry on the 1997 measure; this page describes that framework at a conceptual level only. Stanwood's October 19, 1903 incorporation and its use of the Snohomish County Assessor for parcel/tax information is confirmed via the City of Stanwood's own site (stanwoodwa.org) and Wikipedia. Camano Island's status as unincorporated Island County territory, and the Island County Assessor's combined role valuing both Whidbey and Camano Island property, is confirmed via the Island County government's own site (islandcountywa.gov) and Wikipedia's entry on Camano Island. Camano Island's aggregator-estimated 0.76% median effective property tax rate is sourced from Ownwell and explicitly flagged here as a secondhand estimate, not independently verified. The Stanwood-Camano School District's 11-school, ~4,861-student enrollment and its Camano Island campuses (Elger Bay and Utsalady Elementary) are confirmed via the district's own site (stanwood.wednet.edu) and GreatSchools. This page does not state a specific current combined levy rate or typical annual tax bill for either Stanwood or Camano Island: no figure was verified against a fully-loaded primary source from either county Assessor during this research pass, and this page discloses that as an open gap rather than filling it with an unconfirmed number. The Snohomish County Assessor's Office (snohomishcountywa.gov) and the Island County Assessor's Office (islandcountywa.gov) are the correct sources for current rates and a specific parcel's assessed value. Levy rates, exemption eligibility rules, and taxing district boundaries are set by state law and each county's own administration, and can change from what's described here. This page is independent research, not legal or tax advice; confirm all current figures directly with the applicable County Assessor, the Washington State Department of Revenue, and a licensed Washington tax professional or CPA before making a purchase or relying on any number here for a financial decision.
